Thanks for responding Gwen.
There is sometimes an error in server.log, but it isn't 1 to 1 with the
connection resets on the producer (although this is a socket from that
box). :
[2015-06-30 15:26:09,544] ERROR Closing socket for /10.0.6.244 because of
error (kafka.network.Processor)

Maybe interesting, I also see the following in the server.log with the
mentioned 15-16 minute quiet window:
